Detailsinfo

A vulnerability was found in RoundCube up to 1.0.7/1.1.3 (Mail Client Software) and classified as critical. Affected by this issue is the function set_skin of the file program/include/rcmail_output_html.php. The manipulation of the argument _skin with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Directory traversal vulnerability in the set_skin function in program/include/rcmail_output_html.php in Roundcube before 1.0.8 and 1.1.x before 1.1.4 allows remote authenticated users with certain permissions to read arbitrary files or possibly execute arbitrary code via a .. (dot dot) in the _skin parameter to index.php.

The weakness was released 01/29/2016 (Website). The advisory is available at htbridge.com. This vulnerability is handled as CVE-2015-8770 since 01/12/2016. The attack may be launched remotely. A simple authentication is required for exploitation. Technical details as well as a public exploit are known. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

A public exploit has been developed by High-Tech Bridge SA and been published even before and not after the advisory. The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $0-$5k. By approaching the search of inurl:program/include/rcmail_output_html.php it is possible to find vulnerable targets with Google Hacking.
